16 vision of a toy which is comparatively simple and inexpensive yet durable and elficient in its operation.

A further object of my invention is the provision of a toy which comprises a trough in which exchangeable slides are held for rotation with their end tenons in depressions of the end walls of the trough, and provided with supplementary inscriptions on front and rear faces, which in the state of rest have no 8 meaning but during the rapid rotation of the slides by means of air blown against the same through a tube will supplement themselves to form arithmetical examples, words, legends, or pictures.

provision of a toy equipped with rapidly rotating slides the slightnoise made during the rotation of the slides to simulate the noise of aeroplane propellers, or running automobile engines, as the case may be much to the amusementof children, and the effect of which may greatly be augmented by suitable inscriptions such as for instance What is it '2 or Blow and you will know or the like.

These and other objects and advantages of my invention will become more fully known,

the depressions 13 in the end walls of. the v trough 10 and if now air isblown through the tubular mouth piece 17 against the slide the same will rapidly turn and on slide 20 the full solution of the example3 8=24 will be visible greatly to the amusement and instruction of children, while the-rapid ro tation of slide 25-will result in making the word A M E R I C A visible. The rapid rotation of slide 26 will make the full aeroplane to become visible while the slight noise connected with the rotation will simulate the noise of the propellers etc. a

1 It will be clear that any legend or representation may be placed on'the front and rear sides of slides so as to supplement each other to 'form aperfect legend or picture during f the rapid rotation of the slide as outlined above. r

"It will be understood that I have described and shown the preferred form of my toy and some of the slideswhich are used therewith, as examples of the many possible ways to practically construct mv toy and slides, and that I may make such changes in the general arrangementand the. construction of the minor details thereof as'come within the scope of the appended claims without departurefrom the spirit ofmy invention and the principles involved. 7

Having thus described my invention, what I claim as new and ter's Patent is:
